About Onyx
Onyx builds an open source AI platform that connects to a company's knowledge sources, such as documents, apps and chat, and gives teams search and an AI assistant over that context. The product offers 50+ connectors, source permissions enforced at query time, a choice of LLM providers, and interfaces including a desktop app, MCP, a Slack bot and a Chrome extension. It can be deployed in a customer's cloud, on bare metal, or fully air-gapped.
Customers are enterprise and other organisations that roll the platform out to their teams. A Business cloud plan is priced at $20 per user per month with annual billing, and an Enterprise plan with custom pricing adds SSO, on-premise deployment, dedicated support and an SLA. Ramp is quoted as a customer.
Onyx is based in San Francisco, where it lists open roles in engineering and sales. The company was started by co-founders Chris Weaver and Yuhong Sun, and its investors are listed on the site, including Khosla Ventures and First Round Capital. The open source project lists 20k stars.
Product: Open source enterprise AI search and assistant that indexes company knowledge sources with permission-aware retrieval and supports any LLM.
